To make this "aqua electricity" viable in the real world you would need huge bodies of water penned up and ready to be released at the appropriate time. Like the size of a lake. Pretty ridiculous.
- gherkinnn 7y agoThat body of water also needs to be placed high enough for it to release a waterfall. I can’t think of something. Some large geological structures, perhaps? I dunno. Maybe Elon Musk has a wacky idea to inverse this problem and build tunnels below lakes to make this work.
- bathtub365 7y agoCoquitlam Lake actually has a tunnel leading to Buntzen Lake for the purposes of supplying it with water for power generation. Pipes then carry the water down to a generating station on the ocean shore. https://curiocity.com/vancouver/wp-content/uploads/2019/08/powerhouse.jpg https://curiocity.com/vancouver/wp-content/uploads/2019/08/p...

- jshevek 7y agoThe culture of hackernews is being poisoned by the culture of reddit during this pandemic.
- bathtub365 7y agoWhat is the culture of reddit? I don't read or post there.
- jshevek 7y agoThere are many aspects of the culture of reddit which is poisoning the culture of hackernews during this pandemic, to save time I'll just address the portion of reddit culture that is evidenced here: the practice of pretending to invent something that already exists and naming it in a manner somewhat analogous to its existing name. The is a special case of the culture of repetitive, unimaginative, formulaic humor threads in which a series of people pretend to engage in a conversation in earnest, but the entire thread is satire, or meta, or fake invention, etc. Edit: It seems to me that there is a correlation between the users who participate in these kinds of threads, and the users who damage the culture of HN in other ways. I'm not speaking of the specific users in this particular humor thread, but what I've seen in the past of humor threads in general. Clicking on their profile and viewing past comments, I've found that humor-thread participants often also engage in ideological battle, rely heavily on emotionally manipulative rhetoric, make low quality fallacious arguments, etc.
